My invention relates generally to machinery used in coke producingplants and more particularly to machinery used for leveling the coal inthe chambers of coke ovens and for pushing the coke out of thesechambers.

One of the objects of my invention is to provide a simple andinexpensive and easily and conveniently operable means for leveling coalin the 'chambersof coke ovens and for pushing coke out of thesechambers; to employ one ram to efifect the coal leveling. as well as the'coke pushing; and to provide a coal leveler which properly andefficiently and efiectively levels the coal inchambers which are greaterin width than in height. Other objects will appear, or become apparentor obvious, or will suggest themselves,

during the description of the apparatus shown in the accompanyingdrawings.

In coke producing plants, coal is first charged into the chambers ofcoke ovens, usually through one or more charging openings in the topsthereof, and naturally piles up pyramidically or conically in thechambers; such piling up is quite undesirable since the coal should beleveled so that a coal bed of even thickness is provided before thecoking process begins and thereby effect proper and even coking as wellas proper production of lay-products or elimination of by-productsmaterial from the coal in addition to many other advantages.

The advantages of such leveling is more pronounced in coking chamberswhich are greater in width than in height. The problem to be solved thenis to devise a leveler head or means which levels the coal properly insuch wide ovens or chambers and this problem has been solved in myinvention;

In coke plants prior to my invention, a machine, generally known as acoke pusher, was provided with two rams, one below the other and usuallyto one side of the other for structural and operative reasons, the lowerone had a coke pusher head on one end to push the coke out of the ovenchambers and the upper one had a leveler head on the same end to levelthe coal in the chambers. This structure necessitates that the cokepusher machine (a heavy machine) must be moved sidewisev to bring theleveler head intoproper posi' tion sot-hat the same could enter the doorprovided on'the oven for-that purpose and mustalso be moved sidewisefrom the positions just described to bring-the coke pusher head intoproper position so that the same could enter the door'provided on theovens for that purpose.- Inaddition to this double sidewise movement of.the heavy pusher machine, it is necessary to operate the rams inrdividually. This sidewise movement of the machine as well as theindividual operation of the double ram requires considerable ma'-chinery or mechanism and often results in confusion and consequentpossible accidents by an operator manipulating the wrong lever orsimilar mistakes.

All of the above disadvantages are eliminated and other advantages areadded'in my invention which reducesthe cost of construction and ofupkeep as well as possible mistakes by operators as well as providingmeans i for leveling coal in wide ovens and pushing coke out of ovens inthe most ,eifective and economical manner. I

In order to illustrate my invention, I have embodied the same theaccompanying drawings in a certain device or apparatus. I am aware,however, that, my invention can be embodied in other devices orapparatuses of a similar nature. i

In the accompanying drawings Fig.1 is a plan view of a portion of a cokeplant and shows a portion of a coke oven and a portion of a pushermachine and the ram thereof and a leveler head and a pusher headembodying m inventionas related to other elements of the coke'oven; aportion of the :top of the oven is in section to'more clearly show thesidew se relations between the wide oven chamber and the leveler andpusher heads. p

Fig. 2is a side view of Fig, 1 and shows more clearlythe verticalrelations between elements; the upper portion of the coke oven is shownpartly in sectionto show more clearly how the coal piles up when it'isfirst charged into the chamber; the coke pusher head is shown in fulllines as being extended out of the line 33 in Fig. 2 and shows moreclearly the suspension of the pusher head in the leveler head.

Fig. i is a longitudinal section of the leveler and pusher heads takenin a plane indicated by the line 44: in Fig. 1 and shows more clearlythe suspension of the pusher head in the leveler head and the mechanismfor operating the pusher head which is here shown in full lines asreceded into the leveler head and in dot anddash lines as extended outof the leveler head.

Similar reference characters refer to similar parts throughout theviews.

The coke ovenA has the coking chamber 10 one end of which is closed bythe vertically slidable door 11 which closes the lower portion of thechamber andthe hinged and upwardly swivable door 12 which closes theupper portion of the chamber. The door 12 is to be opened when coal isto be leveled in the chamber and the door 11 is to be opened in additionto the opening of the door 12 when coke is to be pushed out of thechamber.

. Thelarry or coal charging car B has the spout 13 which discharges thecoal C from r t 1e larrv into the chamber throu h the 0 ening 14 whichcoal, naturally, piles up coni- Cally and must be leveled before thecoking process begins to produce an even bed of coal for proper cokingas well as for proper isolation of by-products. The line 15 indicatesthe coal level in the present instance.

The pusher machine D has the ram 16 reciprocatably operated by thetoothed pinion 17 in mesh with the toothed rack 18. The pinion can beoperated by any suitable source of power. i

' The leveler head E is secured to oneend of the ram 16 and is, in thepresent instance,

built up of sheet metal in pyramidal form with the flat walls 19 and 20at each traverse 7 end and the wall portions 21, 22, 23, 24, 25

leveler head, closed all around except at the,

bottom where it is open and the pointed edges 27 and 28and a pluralityof plow-share-like surfaces radiating from these points sothat thesepoints and surfacescan and do scatter the conically piled coal and moveit sidewise and forwardly and backwardly in the manner of a plow andthereby level the coal When the ram is reciprocated in the chamber 10.

The ears'29 of the pusher head F are pivoted on the shaft 30 journaledin the hearing blocks 31 secured to the inner surface of the walls ofthe leveler head. T he body portion 32 of the pusher head extends thefull width of the leveler head and has the stiffening toe 33 and theboss 34 substantially in the middle of the toe.

The shaft 35 is journaled in the bearing blocks 36 secured to the insideof the walls of the leveler-head and the bell crank 37 is carried by theshaft 35 between the blocks 36. The links 38 have one end thereof hingedto the end 39 of the bell crank and the other end thereof hinged to theboss 34.

All of the walls of the leveler head are flush on the bottom andsubstantially in align: ment with the line 15; the leveler head ishollow and open atthe bottom; the shaft 30 is positioned so that theportion 32 of the pusher head is flush with or inside 'ofthe bottom ofthe leveler head; and the'shaft 35 is positioned so that the axis of thecrank 39 is in alignment with the axis of the links 38 and so that thisaligned axis intersects the axesofthe shaf s 30 and 35. This arrangementforms an abutment for the pusher head to prevent the same from swivelingbackwards when the same is pushing coke out of the chamber.

The bar or cable 40 is secured to the end 11 of the bell crank andserves the purpose of raising the pusher head out of the operatingposition thereof and receding the same up into the leveler head. Uponrelease of the cable 40, the pusher head drops down into operatingposition due to the gravity thereof.

When the ram is moved longitudinally toward and into the chamber 10, thepoint 27 digs into the .coal C as indicated in dotted lines and thesurfaces 23 and 24, assisted by the surfaces-21 and 22, move and scattersome of the coal sidewise similar to a plow and also move some of thecoal inwardly of the chamber to level the same in all directions.

When the ram is moved longitudinally in the opposite direction in thechamber, the point 28 and the surfaces 25 and 26 act in a similar mannerbut in an opposite direction and scatter the coal in oppositedirections. Repeated reciprocation of the leveler head eventually levelsthe coal in the chamber properly. During this coal leveling oper ation,the end tl of the bell crank 37 is prac- V tically horizontal, the links38 and the portion 32 are moved up into the hollow of the leveler headso that no mechanism projects or extends below the bottom of the levelerhead; and the cable 40 retains these elements in position. v

After the coking operation or process'is completed, or when the coke isto be pushed out of the chamber, the cable 40 is released whereupon theportion 32 swivels onthe shaft 30 and drops downwardly until the crank39 ber and pushes the same out of the other end of the chamber by meansof the extended pusher head. 1 V

The mechanism shown anddescribed levels coal in coke ovens and. pushescokeout of the ovens in an effective and economical and efiicientandeasily operable manner.
